"Ringtones are patented? Seriously? We haven’t been able to dig up the patent in question, but apparently both Siemens and Sony Ericsson have quietly settled lawsuits filed against them by an inventor who claims to have patented the process by which cellphones play music instead of just a regular ring."I thought all those mono and poly ringtones are played just like the "standard" rings. Or are they talking about actual music files?
